How to access Shibboleth as SP built in variables in your Application?

Most of the variables created by the SP are controlled by you, and correspond to mapped attributes. A few are built into the SP and can't be renamed.

Variable	Meaning
Shib-Application-ID	The applicationId property derived for the request.
Shib-Session-ID	The internal session key assigned to the session associated with the request.
Shib-Identity-Provider	The entityID of the IdP that authenticated the user associated with the request.
Shib-Authentication-Instant	The ISO timestamp provided by the IdP indicating the time of authentication.
Shib-Authentication-Method	The AuthenticationMethod or <AuthnContextClassRef> value supplied by the IdP, if any.
Shib-AuthnContext-Class	The AuthenticationMethod or <AuthnContextClassRef> value supplied by the IdP, if any.
Shib-AuthnContext-Decl	The <AuthnContextDeclRef> value supplied by the IdP, if any.

We can access all these variable as header in JAVA application.

Eg:

    request.getHeader("Shib-Identity-Provider")

   request.getHeader("Shib-Session-ID")

Attribute Authority, Command Line Interface (AACLI)

Today, I have encountered one interesting tool in Shibboleth IdP which will check the resolver, filters and also the metadata so that you can know exactly what will happen in any given situation without starting the IdP. J

As a developer, I would say it’s a great tool as you don’t have to restart your IdP again and again after every changes.

The name of the tool is (Attribute Authority, Command Line Interface) ACCLI which is located in the IDP_HOME/bin directory and is called aacli.sh or aacli.bat.

How it works?

Make sure, you have set IDP_HOME to your system environment variable.

To check what all attribute it will return for userId SysAdmin and Service Provider EntityId “https://domain.waheedtechblog.com/shibboleth”)

aacli.bat --configDir=C:\idp\conf\ --principal=SysAdmin --requester=https://domain1.com/Shibboleth

How to enable multiple domains in Apache Server using Name-Based VirtualHosts and SSL

Scenario: I have an Apache Server(SSL enabled) and tomcat running on my machine and there is one application (app1) hosted on tomcat which is only accessible from Apache Server. You cannot access it directly from tomcat.

Now you want to access app1 using multiple domains i.e. domain1.waheedtechblog.com annd domain2.waheedtechblog.com should point to the same application which is hosted on tomcat.

(I want to implement different Authentication mechanism based on different domains)
Solution: The above case can be achieved using NameBased VirtualHosts and SSL.
First you need to uncomment following lines form ${apache}/conf/httpd.conf file

• LoadModule ssl_module modules/mod_ssl.so
• LoadModule proxy_module modules/mod_proxy.so
• LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
• LoadModule rewrite_module modules/mod_rewrite.so
• LoadModule proxy_http_module modules/mod_proxy_http.so
• Include conf/extra/httpd-ssl.conf

then goto ${apache}/conf/extra/httpd-ssl.conf file add Virtualhost tag for each domain.

Listen 443

NameVirtualHost *:443

<VirtualHost *:443>

DocumentRoot "c:/Apache2/htdocs"

ServerName domain1.waheedtechblog.com

ServerAdmin admin@example.com

ErrorLog "c:/Apache2/logs/error_domain1.log"

TransferLog "c:/Apache2/logs/access_domain1.log"

SSLEngine on

SSLCertificateFile "C:\Apache2\certificate\domain1.crt"

SSLCertificateKeyFile "C:\Apache2\certificate\domain1.key"

ProxyPass / ajp://sp.domain.com:8009/app1/

BrowserMatch "MSIE [2-5]" \

nokeepalive ssl-unclean-shutdown \

downgrade-1.0 force-response-1.0

</VirtualHost>

<VirtualHost *:443>

DocumentRoot "c:/Apache2/htdocs"

ServerName domain2.waheedtechblog.com

ServerAdmin admin@example.com

ErrorLog "c:/Apache2/logs/error_domain2.log"

TransferLog "c:/Apache2/logs/access_domain2.log"

SSLEngine on

SSLCertificateFile "C:\Apache2\certificate\domain2.crt"

SSLCertificateKeyFile "C:\Apache2\certificate\domain2.key"

ProxyPass / ajp://sp.domain.com:8009/app1/

BrowserMatch "MSIE [2-5]" \

nokeepalive ssl-unclean-shutdown \

downgrade-1.0 force-response-1.0

</VirtualHost>

Points to remember:

• Add all DNS entry in system hosts file Eg: for windows (Add “127.0.0.1 domain1.waheedtechblog.com” to “C:\Windows\System32\drivers\etc\hosts”)
• Make sure you are using different certificates and Key for each domain or else it will always point to default VirtualHost i.e. first one that you have defined. Click here on how to generate key and certificate.
• In proxyPass, always ends with '/' or else you will see redirect issue.
